  • the fan By connecting the fan via a bayonet device and / or a latching connection by interposing one or more intermediate elements, as described below, the fan can be changed without tools.
  • the lighting device has a fan adapter as an intermediate element, with which fan adapter the fan is connected or the fan is inserted into the fan adapter, and the bayonet device on the fan adapter and a counterpart of the lighting device , on which counterpart the fan is attached, is arranged.
  • the fan is detachably connected to the fan adapter or is detachably inserted therein.
  • the fan adapter has a receptacle, in which receptacle the fan is releasably fastened / inserted by means of a snap-in connection, clip-in connection or bayonetting device.
  • the fan can be detachably connected to a fan cover as an intermediate element, the fan cover being connectable, for example screwable, to the lighting device.
  • the fan can be releasably connected to a fan cover as an intermediate element, with a bayonet device is provided for releasably connecting the fan to the fan cover.
  • the fan cover is connected to the lighting device, for example to a heat sink for one or more light sources of the lighting device.
  • the fan adapter or the fan cover has at least one air duct so that the air flow can be optimally directed.
  • the object is alternatively achieved with a lighting device according to claim 3, wherein in this alternative the fan is detachably connected to a cover - as an intermediate element - for an opening in the lighting device, the cover being provided with a bayonet device or with bayonet means by means of which it is releasably connected in the opening, the cover having a latching device by means of which the fan is releasably attached to the cover.
  • Figure 1 shows a variant according to the invention of the fastening of a fan 1 in a lighting device 100 in an unassembled state.
  • the fan 1 can be connected to a counterpart 4 by means of a bayonetting device.
  • a fan adapter 3 is provided which has bayonet hooks 2, 2a.
  • the fan 1 is inserted into a corresponding receptacle 3a.
  • the counterpart 4 has bayonet openings 20, 20a, 20b into which the fan adapter 3 with the bayonet hooks 2, 2a is inserted and releasably connected to the counterpart 4 by subsequently rotating the adapter 3. In this way, the fan 1 is releasably connected to the counterpart 4.
  • the counterpart 4 has a central opening 4 'through which air is sucked in axially; it then flows radially out of the fan 1, for which purpose the adapter 3 preferably has radial air ducts, i.e. an air duct 3b.
  • Figure 1a shows the fan off Figure 1 in the installed state, ie in the state attached to the counterpart 4.
  • the counterpart 4 can be designed as a mounting plate, by means of which - for example via corresponding bores 50 - the unit Figure 1a can be connected to a heat sink 105, which carries one or more light sources 110, for example LED light sources (see FIG Figure 1c ).
  • Figure 1c shows a lighting device (headlamp) 100, in which the assembly from Figure 1b is installed in a corresponding opening; It can also be seen that in this embodiment a reflector 120 is provided, which is also connected to the heat sink 105.
  • the adapter 3 can be detached from the rear of the headlight 100 so that the fan 1 can be removed from the adapter 3.
  • Figure 2 shows a variant, not according to the invention, of the fastening of a fan in a lighting device in an unassembled state.
  • a fan cover 5 is provided here, to which the fan 1 can be detachably connected.
  • a locking connection is provided here, consisting of retaining hooks 5a and locking hooks 5b, which protrude from the fan cover 5.
  • the fan 1 has holding sections 1 'and latching sections 1 "which interact with the corresponding hooks 5a, 5b of the fan cover 5 (see FIG Figure 2a ).
  • the latching hooks 5b bend when the fan 1 snaps into place, while the retaining hooks 5a can bend only slightly or not at all;
  • the combination of latching and retaining hooks results in a stable, vibration-proof connection between the fan 1 and the fan cover 5.
  • the fan cover 5 itself is screwed, riveted, etc. to the lighting device, for example, for which purpose in the embodiment shown in FIG Figure 2a and 2 B Corresponding fastening bores 50 are provided on the fan cover 5.
  • the fan is used with the fan cover 5, for example, as in Figure 2b shown attached to a heat sink 105.
  • FIG. 1c shows the entire lighting device 100, the reference numerals 110 and 120 have already been used in connection with Figure 1c discussed.
  • the fan 1 can be released from the rear of the headlight 100 by removing it from the fan cover 5.
  • Figure 3 and 3a show a further variant, not according to the invention, of fastening a fan 1 to a lighting device.
  • the fan 1 can again be releasably connected to a fan cover 5, a bayonet device being provided for releasably connecting the fan 1 to the fan cover 5.
  • the bayonet device includes bayonet hooks 21, which are attached to the fan cover 5, as well as corresponding counterparts 210 on the fan 1.
  • the bayonet device By rotating the fan 1 in relation to the fan cover 5, a detachable connection between these components can be established 1, 5 can be made via the bayonetting device.
  • the 1 fan is held on the fan cover 5 by the bayonet device. Since this only provides two holding points, a hold-down element 31 is provided on the fan cover 5, which holds the fan 1 down on the element 310 in order to prevent the fan 1 from swinging open.
  • a further holding point is provided by a holding hook 51.
  • Figure 3b shows the connection to a heat sink 105 and Figure 3 the entire lighting device 100.
  • the same description and considerations apply here as for Figures 2b and 2c .
  • the fan cover 5 covers the fan 1 towards the headlight 100 and serves as a holder for the fan 1.
  • the air flows through the fan cover 5 and through the fan 1 and occurs in both variants 2 and 3 from the side of the fan 1 (axial suction, radial outlet).
  • Figure 4 shows a further variant not according to the invention, in which the fan 1 is fastened in a fan cover 60.
  • the fan cover 60 has a receptacle in which the fan 1 can be locked by means of a corresponding snap-in connection.
  • the fan 1 has latching elements 40 which, by pushing in and, if necessary, rotating the fan 1, detachably latch into corresponding openings 41 in the fan cover 60 (see FIG Figure 4a ).
  • the fan cover 60 itself is on a counterpart 4, something of a mounting plate similar to that of the Figures 1 and 1 a, the fan cover 60 has corresponding bayonet hooks 51 for this purpose.
  • Figure 4c shows the fan cover 60 with fan 1, bayoneted on the mounting plate 4, which is connected to a heat sink 105 via bores 50, for example.
